Taxa e Duração do Acúmulo de Matéria Seca nos Grãos de Soja e sua Relação com o Rendimento Repositório Alice
COSTA, J.A.; TEIXEIRA, M.C.C.; MARCHEZAN, E..
A identificação de caracteres de fácil e rápida avaliação que estejam associados a altos rendimentos de soja (Glycine max L.) é importante para o melhoramento da cultura. O objetivo deste trabalho foi determinar a taxa e a duração do acúmulo de matéria seca nos grãos de genótipos de soja adaptados ao Rio Grande do Sul e verificar se estes parâmetros estão associados ao rendimento de grãos. O experimento foi conduzido em campo, com irrigação, na Estação Experimental Agronômica da Universidade Federal do Rio Grande do Sul, nos anos agrícolas de 1980181, 81182 e 82183. A irrigação por aspersão foi aplicada durante o período do reprodutivo. Os resultados encontrados mostram que em condição hídrica favorável, com a maxiniização da duração, a taxa de acúmulo de...

Determinacao de aminoacidos em solos de cerrado. Repositório Alice
SOUSA, C.A.S. de; MORHY, L.; OLIVEIRA, S. A. de.
O presente trabalho teve por objetivo identificar os aminoacidos presentes em solos do Distrito Federal. O material peptidico foi extraido dos solos com agua a 100C durante 10 horas, e posteriormente separado por filtracao em gel (Sephadex G-50). Os aminoacidos ocorreram com as seguintes variacoes: glicina - 18,42 a 180,29 nmol/g (media - 104,98 nmol/g); alnaina - 9,18 a 218,77 nmol/g (media - 92,08 nmol/g); serina - 17,43 a 147, 53 nmol/g (media - 60,49 nmol/g); fenilalanina = 12,87 a 192, 40 nmol/g (media - 60,04 nmol/g); prolina - 28,42 a 123,64 nmol/g (media - 56,80 nmol/g); acido glutamico - 19,14 a 148,67 nmol/g (media - 52,40 nmol/g); treonina - 9,41 a 127,74 nmol/g (media- 51,32 nmol/g); valina - 10,54 a 119,65 nmol/g (media - 45,40 nmol/g),...

Obese women on a low energy rice and bean diet: effects of leucine, arginine or glycine supplementation on protein turnover BJMBR
Marchini,J.S.; Lambertini,C.R.; Ferriolli,E.; Dutra de Oliveira,J.E..
This study examined if leucine, arginine or glycine supplementation in adult obese patients (body mass index of 33 ± 4 kg/m²) consuming a Brazilian low energy and protein diet (4.2 MJ/day and 0.6 g protein/kg) affects protein and amino acid metabolism. After four weeks adaptation to this diet, each subject received supplements of these amino acids (equivalent to 0.2 g protein kg-1 day-1) in random order. On the seventh day of each amino acid supplementation, a single-dose 15N-glycine study was carried out. There were no significant differences in protein flux, synthesis or breakdown. The protein flux (grams of nitrogen, gN/9 h) was 55 ± 24 during the nonsupplemented diet intake and 39 ± 10, 44 ± 22 and 58 ± 35 during the leucine-, glycine- and...

Growth characteristics and dynamics of protein synthesis in callus cultures from Glycine wightii (Wight & Arn.) Verdc. Ciência e Agrotecnologia
Silva,André Luis Coelho da; Caruso,Cecília Sulzbacher; Moreira,Renato de Azevedo; Horta,Ana Cecília Góes.
Cotyledon explants were first cultured on MS medium supplemented with 4.52 M 2,4-D and 0.46 mM kinetin. The development of the calli was followed (0, 4, 8, 12, 16, 20, 24, 28 and 32 days after) and the growth curve was determined, based in fresh and dry weight. The growth curve presented sigmoidal form with four distinct phases. The highest growth percentage was observed at the exponential phase and the lowest at the stationary phase. These results indicated that cotyledon callus subculture should be performed 20 days after inoculation. The calli obtained after a period of 28 days were freeze dried, macerated and submitted to extraction with buffers of different pH values (2.6; 4.0; 6.0; 8.0 and 10.0) and the proteins in the extracts were determined by...

15N-labed glycine synthesis Anais da ABC (AABC)
Tavares,Claudinéia R.O.; Bendassolli,José A.; Coelho,Fernando; Sant'ana Filho,Carlos R.; Prestes,Clelber V..
This work describes a method for 15N-isotope-labeled glycine synthesis, as well as details about a recovery line for nitrogen residues. To that effect, amination of alpha-haloacids was performed, using carboxylic chloroacetic acid and labeled aqueous ammonia (15NH3). Special care was taken to avoid possible 15NH3 losses, since its production cost is high. In that respect, although the purchase cost of the 13N-labeled compound (radioactive) is lower, the stable tracer produced constitutes an important tool for N cycling studies in living organisms, also minimizing labor and environmental hazards, as well as time limitation problems in field studies. The tests were carried out with three replications, and variable 15NH3(aq) volumes in the reaction were used...

Glutamate-N-methyl-D-aspartate receptor modulation and minocycline for the treatment of patients with schizophrenia: an update BJMBR
Chaves,C.; Marque,C.R.; Trzesniak,C.; Machado de Sousa,J.P.; Zuardi,A.W.; Crippa,J.A.S.; Dursun,S.M.; Hallak,J.E..
Growing consistent evidence indicates that hypofunction of N-methyl-D-aspartate (NMDA) transmission plays a pivotal role in the neuropathophysiology of schizophrenia. Hence, drugs which modulate NMDA neurotransmission are promising approaches to the treatment of schizophrenia. The aim of this article is to review clinical trials with novel compounds acting on the NMDA receptor (NMDA-R). This review also includes a discussion and translation of neuroscience into schizophrenia therapeutics. Although the precise mechanism of action of minocycline in the brain remains unclear, there is evidence that it blocks the neurotoxicity of NMDA antagonists and may exert a differential effect on NMDA signaling pathways. We, therefore, hypothesize that the effects of...

Fox grape cv. Bordô (Vitis labrusca L.) and grapevine cv. Chardonnay (Vitis vinifera L.) cultivated in vitro under different carbohydrates, amino acids and 6-Benzylaminopurine levels BABT
Carvalho,Dayse Cristina de; Silva,André Luís Lopes da; Schuck,Mariane Ruzza; Purcino,Marivel; Tanno,Guilherme Nakao; Biasi,Luiz Antonio.
The aim of this work was to study the influence of sucrose and glucose, amino acids and BAP (6-Benzylaminopurine) levels on in vitro shoot regeneration of fox grape cv. Bordô and grapevine cv. Chardonnay. The nodal segments from micropropagated material were used as explants and half-strength MS medium as the basal medium. Sucrose and glucose at 15, 30 and 45 g.L-1 were tested as a carbon source and the supplementation of adenine, asparagine, alanine, glycine, cysteine, glutamine, arginine was tested at 40 g.L-1. The BAP levels (1 and 5 μM) in solid and double-phase media were evaluated and compared with a control medium without BAP. Bordô had best in vitro growth than Chardonnay. Sucrose was a better carbohydrate source than glucose for both the...

Effects of the foliar application of methanol on the yield and growth of rice (Oryza sativa cv. Shiroudi) Ciencia e Investigación Agraria
Abbasian,Abouzar; Mirshekari,Bahram; Safarzade Vishekaei,Mohammad N; Rashidi,Varahram; Aminpanah,Hashem.
Effects of the foliar application of methanol on the yield and growth of rice (Oryza sativa cv. Shiroudi). Cien. Inv. Agr. 43(1):17-24. Approximately two decades have passed since it was reported that the foliar application of methanol increased plant biomass and yield. Many subsequent reports have been published concerning the ability or inability to reproduce these initial observations. To evaluate the effect of methanol on rice (Oryza sativa cv. Shiroudi) yield and rice components, a field experiment was conducted at the Tonekabon Rice Research Station in Iran in 2012 and 2013. The experiment had a randomized complete block design (RCBD) with three replicates. The plants were treated with aqueous methanol solutions (0, 6, 12, 18, and 24% (v/v))....
